Enthesitis…is the main cause of the pain, stiffness, and limited range of motion in the spine experienced by AS patients. Enthesitis often presents as swelling over the inflamed area, with patients reporting that the affected area is tender to the touch upon sitting or when touching selected objects. Sitting on hard surfaces can be extraordinarily difficult for a person with AS if the area covering pelvic bones is inflamed .
Patients with AS may also experience peripheral joint synovitis, an inflammation of the synovial joints that occurs in about 50% of AS patients, targeting the hips, knees, ankles, fingers, and toes….It appears to affect not only the synovial lining of the joints [as in rheumatoid arthritis] but it also affects the joint capsule, the enthesitis attachments, and even the lining of the bones….it can affect an entire finger [not just the joints] or toe, and sometimes the locations can be just one, two, or three joints around the body in what seems like a random pattern .

I forgot my anti-inflammatory yesterday.
It feels like fireworks and scatter bombs are going off all over me: fingers, wrists, elbows, shoulders, spine, SI joints, coccyx, feet, toes. Even my scalp hurts today.
